Filed: 1987-11-05
Abstract: PURPOSE:To prevent falling of foreign matter into a photomask or reticule by providing a self-adhesive material having high light transmittance on the inside surface of a pellicle so that the foreign matter sticks thereto. CONSTITUTION:The pellicle film 3 consisting of nitrocellulose having the high average light transmittance at 350-450nm wavelength to be used for exposing is formed on the inside surface of a pellicle frame 2 consisting of Al, etc. The film thickness is so selected that the light transmittance is higher with respect to the desired wavelength; for example, the thickness is selected at 2.85mum with respect to about 436nm+405nm+365nm exposing wavelength. The self-adhesive material 4 consisting of polyfluoro(meth)acrylate particularly having >=50wt.% fluorine content among acrylic fluoropolymers which have lower refractive indices than its film 3 and are not decomposed by light of 350-450nm is provided on the inside surface of the pellicle film 3 and is stuck to the inside surface of the frame 2 as well. The falling of the foreign matter onto the photomask or reticule is prevented and the disturbance of exposing is prevented by this constitution.

Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To equalize collector current and output current of a first transistor of a signal output part with bulk of a current source by offsetting the bulk of base current of the first transistor TR and the bulk of the base current of a second transistor by equalizing them. SOLUTION: A precision current mirror circuit is provided with a loss, in which collector current IQ21 C of the first transistor TRQ21 of a coulometric control part 20, is lost as being supplied to the bases of both transistors QN31, QN32 of a current amplifying part 30. When the size of a first resistor R31 and a second resistor R32 are adjusted properly in consideration of 'β' generated by the difference between an NPN type and a PNP type in view of the loss and characteristics of both transistors QN21 and QN22 of the coulometric control part 20, the bulk of emitter current IQN22 E of the second transistor QN22 of the coulometric control part 20 can be defined as an equation.  Therefore, the bulk of the collector current IQ11C and the output current Iout 3 are equalized with that of the current source Lin by the fact that the bulk of a base current IQ21 B of the first transistor Q21 and that of a base current IQN22 B of the second transistor QN22 in the coulometric control part 20 are equalized and canceled.

Title: Fifo memory control circuit
Inventor: MIZUMOTO EIJI
IPC: G11C7/00
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To automatically make requests for readout and writing to the external circuit. SOLUTION: When the WC terminal is activated, the write address counter 2 increments the writing address to the RAM circuit 1 one by one through the input data s1. Everytime data is written into the RAM circuit 1, the data store counter 4 also carries out an increment and shows the number of effective data stored in the RAM circuit 1 at all times. When the value s10 of the data store counter 4 becomes larger than that of the data limit register s11, the output terminal C for magnitude comparison by the subtractor 12 is made active to make the request to the outside for readout due to the fact that the effective data in the RAM circuit 1 exceeds a desired number through external RREQ. Making the RC terminal active, the external circuit reads out a required number of data from the RAM circuit 1 and receives data through an output data s2.

Title: Method for forming single crystal thin film
Inventor: ASAKAWA TOSHIBUMI
IPC: C30B29/06
Filed: 1993-10-14
Abstract: PURPOSE:To form single crystal thin films on a polycrystalline substrate by a plasma CVD method. CONSTITUTION:A neutral Ne atom flow is mainly formed in the lower direction with an ECR ion-generating device 2. Reaction gases, such as a silane gas, charged from a reaction gas-charging pipe 13 are blown on a SiO2 substrate 11 by the action of a Ne atom flow, and the thin films of amorphous Si grow on the substrate 11 by a plasma CVD reaction. Simultaneously, a part of the highly oriented Ne atom flow is directly applied to the substrate 11, and a part of the other is bent with a reflection plate 12 and subsequently applied to the substrate 11. The reflection plate 12 is designed so that the direction of the Ne atom flow applied to the substrate 11 is perpendicular to the densest surface of the single crystal Si. Therefore, the growing amorphous Si thin films are successively converted into the single crystal Si thin films having uniform crystal axes so that the densest surfaces are disposed perpendicularly to the respective incident directions. The single crystalline thin films are thereby formed on the polycrystalline substrate.
